同时遍历多个数组

python同时遍历两个或更多的序列，可以使用 zip() 组合：

questions=['name', 'question','favorite color']
answers=['lancelot', 'the holod', 'blue']

for q, a in zip(questions, answers):
    print('what is your {0}? It is {1}.'.format(q, a))

oc 额，好像没有

 NSArray *questions = @[@"name", @"question", @"favorite color"];
 NSArray *answers = @[@"lancelot", @"the holod", @"red"];
    
    [questions enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        NSLog(@"what is your %@? It is %@.", obj, answers[idx]);
    }];
